1 Claim.

The object of my invention is to provide a completely concealed sashbalance for a double hung window and to provide simultaneously aWeatherstrip, a parting strip and an all metal jamb lining on which thesash may slide. I attain these objects by means illustrated in theaccompanying drawing.

Figure 1 is an isometric drawing showing a short length of the resilientmetal jamb lining web with the combined sash balance housing and partingstrip, with a sash balance, such as a coil spring, inserted within thecombined sash balance housing and parting strip.

Figure 2 is a section through a jamb of a double hung window frame withtwo sections of my invention applied to the jamb in a manner needed toinstall both the upper and lower sash of a window.

Figure 3 is an isometric view of the bracket which connects the sashbalance and sash.

Figure 4 is a partially cut away isometric drawing without the jamb,showing the jamb lining web with the combined sash balance housing andparting strip with the sash balance connected to the sash.

Similar numerals refer to throughout the several views.

The channel-shaped section consisting of a jamb lining web with thecombined sash balance housing and parting strip, is illustrated inFigures 1, 2 and 4 and is of a resilient sheet metal. The jamb liningweb and back I of the combined sash balance housing and parting strip isfastened to the jamb l2 of the window frame. The combined sash balancehousing and parting strip 2 conceals the sash balance 3 which may be acoil spring. The terminal portion 4 of the combined sash balance housingand parting strip 2 and the flange 5 act as weatherstrips. The spacesimilar parts between the terminal portion 4 of the combined sashbalance housing and partin strip 2 and the jamb lining web I forms arunway 6 in which the bracket 1 slides. At the bottom of the sash 8 isfastened the bracket 1 to which is secured the balance 3 by a hook 9 atthe end of the balance. The top of the balance is fixed near the top ofthe jamb by a metal frictional fastener such as a nail or screw, overwhich the end of the balance is hooked. A rabbet ill at the corner ofthe sash 8 allows for the insertion of the combined sash balance housingand parting strip 2. The lips ll act as a stop between the two sash andcover the joint between the face of the sash and the combined sashbalance housing and parting strip 2.

I claim:

A combined weather strip, parting strip and sash balance housing for adouble hung window comprisin a resilient, sheet metal, channelshapedsection mounted in a window opening so that its web extends verticallyalong the jambyof said pening and having one of its flanges extendingtowards the opposite jamb member and resiliently bearing against theface of one of the vertically sliding sash mounted in said opening theother flange of said section being shaped to form a housing for the sashbalance by having an outside portion extending from the web towards theopposite jamb, an intermediate portion bent to extend towards the firstmentioned flange and a terminal portion bent to extend toward and stopshort of said web to form a vertical runway to accommodate a bracketconnecting the I,

sash balance to the sash, said terminal portion resiliently bearingagainst the opposite face of said sash to form a weather seal andseparate said sash from the other sash.
